Figure 2.5 shows that the framework is steady. Despite the fact that there is a smooth incline it, in the end, draws near to the wanted reaction and stays at a flat zero slant; along these lines making the framework stable. Q2: Is the shape of the closed-loop response consistent with a first-order system. Yes, the first order system shown below is consistent with the closed loop response shown in figure 2.2. Figure 11: First order system Q3 :
How does the change in molten height compare to the change in height of the setpoint?
Figures 2.5 to 2.8 shows that the stature of the molten height contrasts from the setpoint height by the unfaltering state error. The consistent state error for the capacity proceeds at the same rate and does not accelerate or decelerate.
Increase Kp to 10, then larger values such as 100 and 200. Observe the response and note how response characteristics change. Tabulate characteristics for K=200 in table 2 column (e). The steady state error for Kp value of 10 is shown in Figure 2.6. The steady state error for the Kp value of 100 is shown in Figure 2.7. The steady state error for the Kp value of 200 is shown in figure 2.8. Q4: As K increases, describe the effect on response shape
The reaction curve is more straightforward and has less slope as contrasted with the lower k values as K increases. Figures 2.5-2.8 above shows that the as the k values increase, the response curve becomes sharper. In the steady state error, K values above 100 have no significant influence. It is clear when taking a gander at the genuine qualities from the outline yet not exceptionally evident when taking a gander at the chart alone.
As the molten height becomes more and closer the desired height, the K value increases and so is the stability of the function. Figures 2.5 -2.8 shows that the stability is indicated by the time taken to change the value and settle.
